Can This Indian Brain Study Change Mental Healthcare? Inside The CALM-Brain Project

The CALM-Brain database, a first-of-its-kind large-scale indigenous mental health research initiative, is offering new insights into how psychiatric disorders develop, overlap, and respond to treatment, potentially transforming future mental healthcare approaches.

Launched in 2017 by the Rohini Nilekani Centre for Brain and Mind in collaboration with the National Institute of Mental Health and Neurosciences and the National Centre for Biological Sciences, the project has built a cohort of 4,000 to 5,000 individuals.

Researchers have already compiled detailed data from around 2,500 participants in the initial phase.

The longitudinal study examines major disorders, including addiction, bipolar disorder, dementia, obsessive-compulsive disorder, and schizophrenia, with plans to expand further.

Researchers use multiple methods such as clinical assessments, neuroimaging, neuropsychology, electrophysiology, genetics, and environmental analysis, creating a highly comprehensive dataset.

Experts highlight that although neuroscience has advanced in understanding brain function at molecular and structural levels, integrating these layers remains a challenge.

The CALM-Brain initiative addresses this gap by consolidating multi-scale data on a single platform and applying advanced analytical tools.

Participants undergo detailed evaluations over two to three days, including cognitive tests, MRI scans, EEG recordings, and biological sampling.

Researchers will follow participants for up to 20 years to identify early markers of mental illness, distinguish clinical patterns, and improve treatment outcomes.

The study also includes family members to better understand genetic and environmental influences.

Emerging technologies from the project aim to predict individual treatment responses, reducing reliance on trial-and-error prescriptions.

Researchers continue to face challenges, including limited public participation and regulatory barriers in data sharing.

The second National Mental Health Survey is nearing completion, with findings expected to offer crucial insights into mental health trends across India.
